Providing practical examples since 1998

Things look quiet here. But I've been doing a lot of blogging at
dan.langille.org because I prefer WordPress now.
Not all my posts there are FreeBSD related.
I am in the midst of migrating The FreeBSD Diary over to WordPress
(and you can read about that here).
Once the migration is completed, I'll move the FreeBSD posts into the
new FreeBSD Diary website.

This article was originally written when Monolith (ml.org) offerred free dynamic dns
facilities. Unfortunately, Monolith is no longer. So most of this page became
irrelevent.

See the end of this page for other organisations.

What is dynamic DNS?

I've written a bit about DNS already. But most DNS entries assume the IP is
static and will not change on a regular basis. This is fine for machines that are
permanently connected to the Internet and have a static IP address. But most of us
have dynamic IP addresses which change every time we log on. That makes it necessary
to update the DNS entries on a regular basis.
